Is Math Art?
Posted in: Today's ChiliSometimes the results of math are sure beautiful—pretty charts, say, or wonderful visualizations. But can maths itself, those long complex equations, be art too?

How to Build a Möbius Strip Bridge
Posted in: Today's ChiliWe all know about Möbius strips—those 3D shapes surfaces that weirdly only have one side. But how is it possible to build real architectural structures out of a mathematical construct?

YouTube is chock full of falling domino videos, but Numberphile’s Matt Parker may have trumped them all with a complicated 10,000 domino setup that just so happens to function as a very crude computer. How is such a thing even possible? This primer video explains the basics.

Facebook has been working on facial recognition for years to auto-tag photographs, but has now reached a point where its technology is ‘closely approaching human-level performance.’ In fact, in some ways it might even be better.

Recreational mathemusician Victoria Hart—aka Vi Hart—gives overwhelming (and fun!) evidence that clearly demonstrates that Pi is a stupidly common number and the fascination of people with this number is just dumb.

Last week, scientists from the Max Planck Institute for Nuclear Physics published the most exact value ever observed for the weight of a single electron—a value 13 times more accurate than the previous estimate. And the Penning trap, the kooky looking device shown above, was crucial in obtaining this measurement.

Students these days have a lot of resources available at their disposal thanks to the Internet. In fact there is so much out there that most students will never even use a lot of the tools available, and a good example of that is Microsoft Mathematics. This free app covers everything from basic math to precalculus, and can even provide step-by-step explanations for solving math problems. The screenshot above demonstrates what the problem solver looks like including the explanations that are provided for every step. Pretty amazing.
Here’s a rundown on some of the things Microsoft Mathematics is capable of:
- The step-by-step equation solver
Students can use this to learn how to solve difficult math problems. - Graphing calculator
Its full features and large two-dimensional and enhanced three-dimensional color graphs can better illustrate problems and concepts. - Formulas and equations library
Students will find more than 100 commonly used equations and formulae to help identify and apply equations. - Triangle solver
This graphing tool explains triangles and their parts. - Unit conversion tool
Students can use this handy tool to quickly and easily convert units of measure, including length, area, volume, weight, temperature, pressure, energy, power, velocity, and time.
Neat, huh? Imagine doing your homework with this at your side!

You’ve got your Windsor, your half-Windsor, and… well, that’s pretty much it. Except, of course, for the 168,998 other ways that science has determined it’s possible to knot a tie. That’s a thousand times more than we previously thought. All it took to figure it out was a repeat viewing of The Matrix Reloaded.

If you’re curious about what would happen if a perfectly hit cue ball hit a perfectly aligned pool rack perfectly in the middle, well here’s what it will look like. It’s mathematically perfect. Not even the best pool players in the world, magnet breakers or robots can even get it to look like this.

The Evolution of the Meter
Posted in: Today's Chili
Though you’ve likely never given it much thought, a universally accepted unit of measurement like the humble meter is an amazing thing. It lets scientists separated by culture, language, race and even thousands of miles of geography work together on equations and problems like they were sitting next to each other. So how did this unit of measurement come to be?
